I don’t want Jesus to come back, I’d much prefer to see Mars Rover Opportunity rise from the dead. It’s been silent for almost 3 months as a massive dust storm prevented its solar panels from charging, but that storm is finally subsiding, so there’s hope it will recharge and start transmitting again.
It’s been working for 14 years, which is amazing. I’ve had cars that lasted that long, but we brought them in for tune-ups every year. It’s sister robot, Spirit, went dead in 2010. Mars Rover Curiosity landed in 2012 and is still cruising around. These robots are a pretty good deal — I don’t think an astronaut would last anywhere near as long, and he’d be too busy growing poop potatoes to get much science done.
